Water  Me  Bird  (WMB)  by  TinkerElectric.com      

The  Water  Me  Bird  will  tweet  when  your  plant  needs  water!    It  does  this  by  measuring  the  resistance  of  the  soil,  when  it  gets  too  low  the  microcontroller  (brain)  starts  the  chirp  to  let  your  plant  is  thirsty.    Remember  not  to  water  the  electronics.        

   

What’s  in  the  kit:  

 Microcontroller  (brain)  

Find  the  dot  

 U1  

Socket  holder,  find  the  notch  

 SP1  

Buzzer,  find  the  (+)  

 S2  

Switch  

 R1,  R2,  R4  

Resistor  10k  Ω    (Brown,  Black,  Black,  

Red,  Brown)  

 R3  

Resistor  100  Ω      (Brown,  Black,  Black,  Black,  

Brown)  

 Q1  

Transistor  –  Find  the  curved  back  

 

 JP2  

Screw  Terminal  (holes  face  outward)  

 

 D1  

LED  –  Find  the  short  side

 COIN  

Battery  holder  

 3V  Battery  CR2032  Type  

 Bird  PCB  

Printed  Circuit  Board  

     

Metal  rods  (2)  

   

Construction:  1. Solder  R3  100 Ω  resistor  (Brown,  Black,  Black,  Black,  Brown)  2. Solder  R1,R2  and  R4  10k Ω  resistor  (Brown,  Black,  Black,  Red,  Brown)  3. Solder  Q1  Transistor.  Remember  to  align  the  flat  side.  4. Solder  U1  the  socket  holder.  Align  the  notch  to  the  front  

 5. Solder  S2.  Note  the  legs  come  out  on  the  left  and  right  6. Solder  SP1.  Align  the  (+)  with  that  on  the  board  7. Solder  COIN.  The  battery  holder  has  a  distinct  circle  to  be  aligned.  8. Solder  D1.  Note  the  red  plastic  has  a  flat  side  that  aligns  with  the  marker.  

Flat  side  to  the  right.  9. Solder  JP2.  Note  the  open  holes  face  down.  They  will  hold  the  metal  rods.  10. Unscrew  the  terminals  JP2  to  allow  for  the  size  of  the  rods.  Screw  the  

metal  rods  into  JP2  on  the  left  and  right.  Leave  the  middle  one  empty.  11. Note  the  microcontroller  has  a  notch  and  dot  at  the  front.  Align  this  with  

the  front  of  U1  on  the  board.  When  inserting  it  ensure  the  legs  don’t  bend.  12. The  coin  battery  is  to  have  the  (+)  face  upward.  Insert  the  battery.  

 

Operation  1. Insert  the  birds  legs  into  DRY  soil  2. Press  the  button  to  tell  it  what  dry  is  3. Water  your  plant,  the  bird  will  then  go  to  sleep  

Front,  notch  here

Trouble  shooting  • No  sound  or  light  –  check  battery  (+)  is  face  up.  Ensure  microcontroller  

has  the  notch  facing  left.  Ensure  LED  has  flat  side  on  the  right.  • No  light,  but  tweets  -­‐  Ensure  LED  has  flat  side  on  the  right.  • No  tweet  but  light  –  Ensure  speaker  has  (+)  at  top  • Tweets  once  then  nothing  –  The  bird  thinks  it  is  wet.  Place  it  in  soil,  then  

press  the  button  to  tell  it’s  dry.  Chirping  should  begin.  Then  water  plant  and  chirping  will  stop.  

• Check  transistor  is  correctly  aligned  for  any  other  issue
